This script is Copyright (C) 2006-2017 Tenable Network Security, Inc.


Synopsis :

The remote application is prone to denial of service attacks.

Description :

The remote host appears to be running CommuniGate Pro, a commercial
email and groupware application.

The version of CommuniGate Pro installed on the remote host includes
an LDAP server that fails to handle requests with Distinguished
Names (DNs) that contain too many elements. A user can leverage this
issue to crash not just the LDAP server, but also the entire
application on the remote host.
